Subject: [PATCH] Do not adjust the shebang of Python scripts for
 cross-compilation

The copy_scripts() method in distutils copies the scripts listed in
the setup file and adjusts the first line to refer to the current
Python interpreter. When cross-compiling, this means that the adjusted
shebang refers to the host Python interpreter.

This patch modifies copy_scripts() to preserve the shebang when
cross-compilation is detected.
